These are services listed in the smb.conf file, and found to exist through checks in this code. Note that added will be incremented on the basis of the number of services added. svc_ptr should have enough memory allocated to accommodate all of the services that exist. Typically _svcctl_num_external_services is used to "size" the amount of memory allocated, but does little/no work. enum_external_services() actually examines each of the specified external services, populates the memory structures, and returns. ** note that 'added' may end up with less than the number of services found in _num_external_services, such as the case when a service is called out, but the actual service doesn't exist or the file can't be read for the service information. ********************************************************************/ WERROR enum_external_services(TALLOC_CTX *tcx,ENUM_SERVICES_STATUS **svc_ptr, int existing_services,int *added) { /* *svc_ptr must have pre-allocated memory */ int num_services = 0; int i = 0; ENUM_SERVICES_STATUS *services=NULL; char **svc_list,**svcname; pstring command, keystring, external_services_string; int ret; int fd = -1; Service_info *si; TDB_DATA key_data; *added = num_services; if (!service_tdb) { DEBUG(8,("enum_external_services: service database is not open!!!\n")); } else { pstrcpy(keystring,"EXTERNAL_SERVICES"); tdb_lock_bystring(service_tdb, keystring, 0); key_data = tdb_fetch_bystring(service_tdb, keystring); if ((key_data.dptr != NULL) && (key_data.dsize != 0)) { strncpy(external_services_string,key_data.dptr,key_data.dsize); external_services_string[key_data.dsize] = 0; DEBUG(8,("enum_external_services: services list is %s, size is %d\n",external_services_string,key_data.dsize)); } tdb_unlock_bystring(service_tdb, keystring); } svc_list = str_list_make(external_services_string,NULL); num_services = str_list_count( (const char **)svc_list); if (0 == num_services) { DEBUG(8,("enum_external_services: there are no external services\n")); *added = num_services; return WERR_OK; } DEBUG(8,("enum_external_services: there are [%d] external services\n",num_services)); si=TALLOC_ARRAY( tcx, Service_info, 1 ); if (si == NULL) { DEBUG(8,("enum_external_services: Failed to alloc si\n")); return WERR_NOMEM; } #if 0 /* *svc_ptr has the pointer to the array if there is one already.
